Effect of Modes of Rolling on Evolution of Texture and Yield Locus Anisotropy in a Multifunctional Ti-31Ta-12Nb-2V-8Zr-0.22O Alloy

Abstract

Present work describes the evolution of texture during different modes of deformation by cold rolling of a Gum metal or multifunctional β titanium alloy. The starting and cold rolled materials exhibit the presence of β and β with small amount of stress induced martensitic (α˝) phases, respectively. The development of texture has been explained in terms of α and γ fibres. The bulk hardness appears to be independent of modes of deformation by cold rolling. The yield surfaces of as received and solution treated samples exhibit marked anisotropy which persists during different modes of deformation by rolling.
